Properties and stability

Colorless oily liquid.

It has a refreshing and sweet floral fragrance, with a refreshing feeling and a permeable aroma. Like propionate, it has been widely used more than 60 years ago In the formulas of various flavors.

Storage method

Store in a cool and ventilated place.

Synthesis method

Carve alcohol obtained by oxidation of limonene or reduction of carvone is obtained by acetylation.

Purpose

The ester structure has a softer aroma than carvone, and also has an herbal aroma, so it can be used in candies, chewing gums, baked goods, cold drinks, etc., and can be used as spearmint in daily chemical essences. It is used as a modifier, synergist, and harmonizer for fragrance, mint, and certain floral fragrances.
